The chamber includes first and second distal ends disposed at two opposite ends, and first and second lateral sides disposed at two opposite sides. The chamber further includes a gas inlet hole and an air inlet hole, which are disposed at the first distal end. Furthermore, the chamber includes a first channel connecting with the gas inlet hole and the air inlet hole and includes a first compartment connecting with the first channel.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a burner of a gas device.

2. Description of the Related Art

A conventional burner generally includes a plurality of air inlet holesand a plurality of flame exit pores. Generally, each air inlet hole isof the same size with each flame exit pore.

Taiwan Pat. No. 1306498 discloses a burner for a gas device. The burnerincludes an inlet port, a passage, a plurality of air inlet holes, and aplurality of flame exit pores. Gas is to be directed into the burnerthrough the inlet port and flows in the passage thereafter. Air is to beintroduced into the burner through each air inlet hole for mixing withthe gas in the passage. A flame, which is provided by combustion of amixture of the gas and the air in the passage, can exit each flame exitpore. Each air inlet hole is designed to have a greater size than eachflame exit pore. Therefore, air is introduced into the burner througheach air inlet hole due to negative pressure effect. In contrast to theconventional burner that includes each air inlet hole having the samesize with each flame exit pore, each air inlet hole and each flame exithole of I306498 are different in size. Specifically, the air inlet holeis intended to be bigger for allowing a greater amount of air to beintroduced into the burner, thereby alleviating a common incompletecombustion problem. However, the gas near the inlet port is still notmixed with the air thoroughly, thereby creating red flames in a regionnear the inlet port and resulting in an incomplete combustion in thatregion. Another problem is that the density of gas near a region faraway from the inlet port is low as compared to that near the inlet port,thereby resulting in weak frames in that region.

The present invention is, therefore, intended to obviate or at leastalleviate the problems encountered in the prior art.

SUMMARY OF THE INVENTION

According to the present invention, a burner of a gas device includes afirst plate, a second plate engaged with and disposed opposite to thefirst plate, and a chamber formed by the first and second plates andpartially delimited in the first plate and partially delimited in thesecond plate. The chamber includes first and second distal ends disposedat two opposite ends, and first and second lateral sides disposed at twoopposite sides. The chamber further includes a gas inlet hole forallowing gas to enter into the chamber, which is disposed at the firstdistal end and includes an air inlet hole for allowing air to enter intothe chamber, which is disposed at the first distal end.
